What is Schema Markup?
Schema markup (structured data) is code added to your web pages that helps search engines understand your content. Implemented as JSON-LD, it can trigger rich results in search — star ratings, FAQ dropdowns, pricing, and more.
Common schema types:
- Organization: Brand info, social profiles - Article/BlogPosting: Author, dates, publisher - FAQPage: Questions and answers (doubles SERP real estate) - Product: Price, availability, reviews - BreadcrumbList: Navigation hierarchy - SoftwareApplication: Features, pricing, ratings - LocalBusiness: Address, hours, services - Person: Author credentials, social profiles
Validation: Use Google's Rich Results Test to verify implementation. Schema must be valid JSON-LD and match the visible page content.
Example
A product page with Product schema showing price ($299/mo), availability (in stock), and reviews (4.8 stars) gets a rich result in Google — with price and rating visible directly in the search listing.
